SAW-VISE.

SPECIFICATION forming part of Letters Patent No. 635,907, dated October31, 1899.

Application filed February 16, 1899. Serial No. 705,691. (No model.)

To all whom it may concern:

Be it known that I, HENRY ARMSTRONG, of Rochester, in the county ofMonroe and State of NewYork, have invented certain new and usefulImprovements in Saw-Vises; and I do hereby declare the following to be afull,clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, and tothe reference-numerals marked thereon.

My present invention relates to saw-Vises, and particularly to thatclass adapted for holding circular saws while being sharpened or set,and has for its object to provide ameans for supporting the saws andpermitting their rapid insertion and removal and also their adj ustmentto bring the different portions into proper position, and, further, hasfor its object to provide a vise that is capable of adjustment to varythe angle of the saw relative to a horizontal plane, whereby the edgesof the teeth may be readily sharpened at the proper angle.

To these and other ends my invention consists in certain improvementsand combinations of parts, all as will be clearly described, and thenovel features pointed out in the claims at the end of thisspecification.

In the drawings, Figure l is a front elevation; Fig. 2, a longitudinalsectional View on the line a: a: of Fig. 1; Fig. 3, a similar Viewshowing the vise opened to receive a saw; Fig. 4, a sectional view onthe line y y of Fig. 2; Fig. 5, a similar View on the line 22 of Fig. 2.

Similar reference-numerals in the different figures indicate similarparts.

In the present embodiment of my invention I employ a vise adapted to besecured to a bench-top or other support and consisting of movable andstationary jaws 2 and 3, pivoted together by a pin 4 at their lower endsand having the plain engaging surfaces 5 upon their upper extremities,between which a sawplate (indicated by 6) is secured. The jaws arelocked, engaging the saw, as described, by means of wedge-surfaces 14,formed on a block or slide 7, movable in guides 7 on the jaw 2 andcooperating with the inclined surfaces of notches 50, formed upon eachside of the outer end of a stud or pin 8, adjustably secured to the jaw3 and extending through a slot or elongated aperture 9 in the jaw 2 tothe front side of the vise.

10 indicates a handle, pivoted at 11 to the movable jaw and providedwith a curved slot 12, open at the end, and in which latter is arrangeda stud 13, connected to the lower end of the slide 7, carrying thewedges 14, said parts operating, as the handle is raised, to more thewedges out of engagement with the pin and permit the separation of thejaws.

When a circular saw is placed in the vise,

the pin 8 projects through the arbonaperture at the center and supportsthe saw, with its teeth, above the edges of the jaws, and toaccommodatesaws of various diameters so that the teeth may always besupported at the proper height I provide an elongated slot 15 in therear jaw, and upon the pin 8 are also provided guides 16 and a foot orextension 17, adapted to slide in the slot and to cooperate with aclamping-screw 18, whereby the pin may be held in any desired positionof adj ustment. A slot 9 is provided in thefront jaw 2, corresponding tothe slot 15 in the stationary jaw, and a corresponding slot is formed inthe: slide 7, through which the stud projects, permitting the verticalmovement of the wedges to clear the pin and allow the outer jaw to betilted back upon the pivot 4, as shown in Fig. 3, thereby permitting theready removal or insertion of a saw.

In order that the saw may be held at an angle, so that the file may beheld more nearly horizontal while sharpening the sides of teethas, forinstance, the teeth of crosscutsaWsI provide a pivotal connectionbetween the bench or support and the rear side of the vise, consisting,preferably, as shown in the present instance, of a perforated lug orboss formed upon the rear of the jaw 3, pivoted upon the pintle 20,extending through similar ears or lugs 21, formed upon a plate 22, whichis adapted to be secured to the benchtop by screws or in any othersuitable manner. A pivoted link 23, pivoted upon a pin 24 between lugs25 on the lower end of the vise, is adapted to extend beneath thesupport 1 and cooperate with a shoulder 26 and locking-nut 27 thereon,operating through a slot 28 in the link, whereby the vise may be tiltedto any desired position and secured by tightening the locking-nut.

In the vertical sectional views I have shown an aperture 30, which maybe provided in the rear jaw near its upper end to receive a pin or stud(shown in dotted lines, Fig. 2) and positioned to support circular sawssmaller in diameter than those for which the larger sizes of vises areadapted.

The upper ends of the jaws are rounded to conform to the circumferenceof the saw, allowing several teeth to be sharpened ata single clamping;but the device could be adapted equally well for holding straight sawsif the en gaging ends of the jaws were formed straight across the top.

This device is particularly adapted to be made of cast-iron, and theparts being few and of simple construct-ion very little labor isrequired in uniting them. The handle is pivoted upon the pin 11, formedat the side of the movable jaw, and the latter has a lug or projection.51 cast thereon to prevent the accidental removal of the handle; but anotch 31, formed in the handle at the side of the hearing, permits thehandle to be applied or removed by bringing the notch into register withthe lug, when the latter may be passed through the former, and thehandle when in the normal position is held securely upon the pin. Theopen-ended slot 12 permits the easy removal of the handle fromengagement with the pin 13 when the latter is raised into the verticalposition.

The operation will now be readily understood. The jaws being separated,the saw is placed upon the pin 8, which is then adj usted vertically tobring the saw-teeth into the desiredpositiomand secured by the clamping-nut 18. The handle 10, pivoted to the movable jaw, is raised,carrying with it the bearing-pin 13, moving the latter and the wedges 1%on the slide 7 vertically until above the pin, when the jaws may beclosed, and by dropping the handle the wedges engage the notches 50 inthe pin, locking the jaws and securing the saw.

By employing the wedges as a locking means I am enabled .to greatlysimplify the device, and by pivoting the handle in the detachable mannerdescribed the vise is capable of being packed into small compass andreadily set up when desired for use.

It will be seen that the handle serves not only as an operating meansfor the locking mechanism, but also as a handle for opening and closingthe movable jaw, and the same serves to operate both movements andallows the device to be manipulated quickly.

I claim as my invention- 1. In a vise, the combination with a stationaryjaw and a movable jaw pivoted thereto, of an interlocking memberarranged rigidly upon the first-mentioned jaw, and a looking membersliding upon the other jaw adapted to. engage with the other member.

2. In a vise, the combination with a pair of pivoted jaws, of a pinsecured to one of the jaws and having shoulders thereon, of a lookingmember sliding upon the other jaw and engaging the shoulders on the pin.

3. In a vise, the combination with a pair of pivoted jaws, of a pinadjustably mounted upon one of the jaws and having shoulders thereon,and a locking member sliding upon the other jaw and adapted to engagetherewith.

4. In a vise, thecombination with a pair of pivoted jaws, of a pinadjustably secured upon one of the jaws and having shoulders adapted tobe engaged by a movable locking means carried upon the other jaw.

5. In a vise, the combination with a pair of jaws, of a pin adj ustablysecured toone of the jaws and having a shoulderthereon, of a movablewedge carried upon the other jaw and adapted to cooperate with theshoulder on the pin.

6. In a vise, the combination with a pair of pivoted jaws and a pinmounted upon one of the jaws and having shoulders thereon, of a platehaving the wedges and sliding in ways upon the other jaw, and anoperating-handle pivoted to the said jaw and connected to the plate.

'7. In a vise, the combination with a Stationary jaw and a movable jawpivoted thereto, of a pin adjustable in a slot in the stationary jaw,and a corresponding slot in the movable jaw through which the pinprojects, guides upon the latter jaw arranged at the sides of the slot,and a plate sliding therein.

8. In a vise, the combination of the two jaws pivoted together, one ofsaid jaws having a pin adjustably secured thereon, alocking-platemovable upon and carried by the other jaw, and a wedge connectionbetween said plate and pin.

9. In a vise, the combination of the two jaws pivoted together, one ofsaid jaws having a pin rigidly secured thereto, a lockingplate movableupon and carried by the other jaw, a wedge connection between said pinand plate, and a handle connected to said plate for causing itsoperation and controlling the movement of the jaw.

10. In a saw-vise, the combination with the cooperating jaws having therecesses or sockets near their upper ends for the reception of aremovable pin, of an adjustable pin or sawsupport extending between thejaws, and means for clamping the jaws.

11. In a vise, the combination of the stationary jaw, the adjustable pinthereon having the engaging projections at its end, the movable jawhaving the longitudinal slot, the slotted plate sliding on the movablejaw, a wedge connection between the pin and plate, the handle pivoted onthe movable jaw, and the slot-and-pin connection between said handle andsliding plate.

12. The combination with the jaws pivoted together, one jaw having thelocking-pin and the aperture through which the pivotpin extends.
